RELATED APPLICATION

This application is a continuation application of PCT Patent Application No. PCT/CN2021/077446, filed on Feb. 23, 2021, which claims priority to Chinese Patent Application No. 202010268946.1, filed with the National Intellectual Property Administration, PRC on Apr. 8, 2020, each of which is incorporated by reference in its entirety.

FIELD OF THE TECHNOLOGY

This application relates to the technical field of computers, and in particular, to a data synchronization method and apparatus, a terminal, a server, and a storage medium.

BACKGROUND OF THE DISCLOSURE

With the development of multimedia technologies and diversification of terminal functions, more and more types of games can be played on a terminal. The shooting game is a popular game. The terminal may display a virtual scene in an interface and display a virtual object in the virtual scene. The virtual object may control a virtual prop to fight with other virtual objects.

Currently, by using the virtual prop with explosive power as an example, a control method for the virtual prop is usually is to throw the virtual prop to a certain location after a user clicks an interactive button. When the virtual prop falls onto the ground, the explosion effect of the virtual prop can be displayed at the drop point. In the process, the virtual prop rebounds when colliding with the virtual obstacle on the movement trajectory. The terminal and the server both calculate the movement trajectory of the virtual prop. If the calculated results are not the same, the movement trajectory and the drop point calculated by the server shall prevail, so as to display the explosion effect.

Since some virtual scenes or angles in the terminal and the server cannot be completely the same, it cannot be ensured that the movement trajectories of the virtual prop calculated by the terminal and the server are completely the same. In this way, the movement trajectory calculated by the server shall prevail. The inconsistency of the movement trajectories calculated by the terminal and the server is also likely to cause the inconsistency of the location of the finally displayed explosion effect and the drop point. For example, finally, the drop point calculated by the server shall prevail. A situation may occur during the display of the explosion effect of the virtual prop: the virtual prop falls at one location while the explosion location is at another location. As a result, the movement trajectory of the virtual prop acquired in the foregoing control method is inaccurate, which does not conform to the actual movement of the virtual prop.

The following embodiment is described by using an example that the terminal includes a smartphone.

A person skilled in the art may learn that there may be more or fewer terminals. For example, there may be only one terminal, or there may be tens of or hundreds of or more terminals. The quantity and the device type of the terminals are not limited in the embodiments of this disclosure.

FIG. 2 is a flowchart of a data synchronization method according to an embodiment of this disclosure. Referring to FIG. 2, the method may include the following steps.

201: A terminal controls, in response to a throwing operation on a virtual prop, the virtual prop to move in a virtual scene according to a first movement trajectory.

The virtual prop is a prop that can interact with a virtual object. A user may operate on the terminal to control the virtual object to use or control the virtual prop in the virtual scene. In the embodiment of this disclosure, the user may perform a throwing operation. The terminal can acquire, in response to the throwing operation, a first movement trajectory of the virtual prop and control the virtual object to throw the virtual prop when detecting the throwing operation, so that the virtual prop can move according to the first movement trajectory.

An initial throwing angle, an initial throwing direction, and an initial throwing strength corresponding to the first movement trajectory are manually adjusted by the user by using the throwing operation.

For example, the virtual prop may be throwing props such as grenades, cluster munitions, smoke grenades, stun grenades, frangible grenades, sticky grenades, or the like. A type of the virtual prop is not specifically limited in the embodiments of this disclosure. By using the grenades as an example, the user may select the grenade, press a throwing button, and release the throwing button in a case that a proper throwing angle is adjusted. The terminal may control the virtual object to throw the grenade according to the current throwing angle. In this way, the grenade can fly through the air according to the first movement trajectory corresponding to the current throwing angle.

202: The terminal acquires collision information and movement information of the virtual prop in response to a collision between the virtual prop and a virtual obstacle on the first movement trajectory.

The virtual obstacle may exist on the first movement trajectory. In a case that the virtual prop collides with the virtual obstacle, the virtual prop rebounds and changes a movement trajectory. The virtual obstacle may be the virtual object in the virtual scene. For example, the obstacle may be a wall, a box, a vehicle, or the like, or may be the virtual object in the virtual scene. Alternatively, the virtual obstacle may be fixedly set in a virtual environment. Alternatively, the virtual obstacle may be movable in the virtual environment.

The collision information is used for indicating related information of a current collision, for example, collision location information, the collision location information and type information of the virtual obstacle, or the like. The movement information of the virtual prop may be the movement information of the virtual prop when the collision occurs, during the collision or after the collision, which is not limited in the embodiments of this disclosure.

Optionally, the movement information of the virtual prop may be used for indicating a movement situation of the virtual prop. For example, the movement information may be movement velocity information of the virtual prop. The movement velocity information may be a movement velocity during the collision of the virtual props, or may be a movement velocity after the collision, which is not limited in the embodiment of this disclosure. The movement velocity information is represented by a vector (including a velocity magnitude and a direction).

It may be understood that, the first movement trajectory of the virtual prop after the collision can be determined based on the collision information and the movement information, so as to control the virtual prop to continuously move according to the first movement trajectory. Definitely, after the first movement trajectory after the collision is learned, a location of the virtual prop during releasing can also be determined. Therefore, the virtual prop may be controlled to release at the location.

203: The terminal transmits, to a server, synchronization information including the collision information and the movement information, the synchronization information being used for instructing the server to correct a second movement trajectory according to the collision information and the movement information, the second movement trajectory being a movement trajectory of the virtual prop acquired by the server.

The first movement trajectory is determined by the terminal. The second movement trajectory is determined by the server. Since some virtual scenes or angles in the server and the terminal cannot be completely the same, the first movement trajectory and the second movement trajectory may be different from each other.

In the embodiments of this disclosure, in a case that the virtual prop collides with the virtual obstacle, the terminal can acquire and synchronize the collision information and the movement information of the virtual prop to the server, to inform the related information of the current collision. Then the server may correct, based on the collision-related information synchronized by the terminal, the second movement trajectory acquired the server. The corrected second movement trajectory is the same as the first movement trajectory in the terminal.

In addition, by using the foregoing steps, the movement trajectory of the virtual prop in the terminal is the same as that in the server. A release location of the virtual prop is determined by using the same movement trajectory, that is, a target release location. Results acquired by the server and the terminal are the same. Since the information synchronization during the collision between the terminal and the server corrects the second movement trajectory in the server, the target release locations subsequently acquired are also the same. The virtual prop can be released at a real location of the virtual prop, thereby improving the accuracy of the display location of the release effect.

In the embodiments of this disclosure, in a case that the virtual prop collides with the virtual obstacle on the first movement trajectory during the movement according to the first movement trajectory, the collision information and the movement information of the virtual prop are synchronized to the server, so that the server may correct, according to the synchronized collision information and movement information, the second movement trajectory acquired by the server. In the foregoing data synchronization method, the movement trajectory of the virtual prop in the server is corrected by synchronizing the collision information and the collision-related movement information of the virtual prop, so as to be synchronized with the movement trajectory in the terminal. In this way, the movement trajectory of the virtual prop in the server is the same as that in the terminal, thereby enhancing the accuracy of the movement trajectory of the virtual prop. In addition, the movement trajectories obtained by the server and the terminal are the same, and drop points calculated by using the same movement trajectory are also the same. In this way, the release effect of the virtual prop can be displayed at the drop point. FIG. 3 is a flowchart of a data synchronization method according to an embodiment of this disclosure. Referring to FIG. 3, the method may include the following steps.

301: A server acquires a second movement trajectory of a virtual prop in response to a throwing instruction on the virtual prop.

The throwing instruction may be transmitted by a terminal in response to the throwing operation on the virtual prop. For example, a user may perform the throwing operation on the terminal. The terminal may transmit the throwing instruction to the server in response to the throwing operation when detecting the throwing operation, to notify the server that the virtual prop is thrown. The server may acquire the second movement trajectory of the virtual prop after receiving the throwing instruction.

In a possible implementation, the throwing instruction may include throwing parameters such as a location where the virtual prop is thrown, a throwing angle, a throwing direction, a throwing strength, and the like. The server may also extract the throwing parameters from the throwing instruction, so as to determine the second movement trajectory according to the throwing parameters. A process of acquiring the second movement trajectory is similar to a process of acquiring the first movement trajectory by the terminal in step 201, and the details are not described herein again.

302: The server receives synchronization information transmitted by a terminal, the synchronization information including collision information and movement information of the virtual prop and being transmitted by the terminal in a case that the virtual prop collides with a virtual obstacle on a first movement trajectory, the first movement trajectory being a movement trajectory of the virtual prop acquired by the terminal.

In the terminal, the virtual prop moves according to the first movement trajectory. The virtual prop may collide with the virtual obstacle on the first movement trajectory. In a case that the collision occurs, the terminal can perform steps 202 and 203. The synchronization information including the collision information and the movement information of the virtual prop is transmitted to the server, thereby implementing the synchronization of the collision-related information. In this way, the server can receive the collision information and the movement information. The second movement trajectory after the collision of the virtual prop is determined according to the collision information and the movement information. The second movement trajectory determined according to the collision information and the movement information may be different from the second movement trajectory in step 301. Therefore, step 303 may be performed to use, as a correction basis of the second movement trajectory, the synchronization information transmitted by the terminal.

In a possible implementation, the server may also determine, according to the second movement trajectory and the virtual scene after performing step 301, whether the second movement trajectory includes the virtual obstacle. In turn, it can be determined whether the virtual prop collides with the virtual obstacle on the second movement trajectory, and the collision information and the movement information are acquired in a case that it is determined that the collision occurs.

In the implementation, the server may compare, with the collision information and the movement information acquired by the server, the collision information and the movement information synchronized by the terminal, to determine whether the collision information and the movement information synchronized by the terminal and the collision information and the movement information acquired by the server are the same. If so, the server may not perform step 303 below, and directly acquire the second movement trajectory after the collision according to the collision information and the movement information. If not, step 303 is then performed to re-determine the second movement trajectory, so as to correct the original second movement trajectory.

The server may further update the collision information and the movement information acquired by the server. In this way, the collision information and the movement information of the virtual prop in the terminal and the server are the same. The movement trajectories of the virtual props are also the same. Therefore, the target release locations determined subsequently according to the movement trajectories are also the same.

303: The server corrects the second movement trajectory according to the collision information and the movement information.

By using the foregoing steps, the server receives the collision information and the movement information synchronized by the terminal. The movement trajectory of the virtual prop after the collision may be determined according to the collision information and the movement information, that is, the second movement trajectory is corrected. The second movement trajectory is corrected based on the collision information and the movement information synchronized by the terminal. In this way, the collision information and the movement information of the virtual prop in the terminal and the server are the same. Correspondingly, the first movement trajectory and the second movement trajectory of the virtual prop are also the same. Therefore, the target release locations subsequently determined by using the movement trajectories are also the same.

In a possible implementation, after the data synchronization by using the method provided in the embodiments of this disclosure, the server may determine the target release location based on the corrected second movement trajectory. Since the first movement trajectory and the second movement trajectory are the same, the virtual prop can move to the target release location according to the first movement trajectory. In this way, the terminal may display a release effect according to the target release location. A location of displaying the release effect is the same as the location where the virtual prop is located, so as to ensure the accuracy of displaying the release effect, and the virtual prop can be released at the drop point.

In a possible implementation, the virtual prop may collide with a plurality of virtual obstacles during the movement according to the first movement trajectory. The terminal may synchronize the collision information and the movement information to the server after each collision. The server may correct the second movement trajectory of the virtual prop according to the collision information and the movement information synchronized by the terminal. In this way, the second movement trajectory of the virtual prop in the server and the terminal is the same as the first movement trajectory. Specifically, a process of correcting the second movement trajectory every time is similar to that in step 303. The number of collisions is not limited in the embodiment of this disclosure.

In the embodiments of this disclosure, after the virtual prop is thrown, the server may acquire the second movement trajectory of the virtual prop. In a case that the virtual prop collides with the virtual obstacle during the movement, the terminal may synchronize the collision information and the movement information of the virtual prop to the server, so that the server may correct, according to the synchronized collision information and movement information, the second movement trajectory acquired by the server. In the data synchronization method, the movement trajectory of the virtual prop in the server is corrected by receiving the collision-related information synchronized by the terminal, so as to be synchronized with the movement trajectory in the terminal. In this way, the movement trajectory of the virtual prop in the server is the same as that in the terminal, thereby enhancing the accuracy of the movement trajectory of the virtual prop. In addition, the movement trajectories obtained by the server and the terminal are the same, and drop points calculated by using the same movement trajectory are also the same. In this way, an explosion effect can be displayed at the drop point.

FIG. 4 is a flowchart of a data synchronization method according to an embodiment of this disclosure. In this embodiment, the process of two methods is described in the form of interaction between the terminal and the server. Referring to FIG. 4, the method may include the following steps:

401: A terminal controls, in response to a throwing operation on a virtual prop, the virtual prop to move in a virtual scene according to a first movement trajectory.

A user may acquire the virtual prop by operating and controlling a virtual object. The terminal may display the virtual prop at a corresponding location of the virtual object in the virtual scene. For example, the virtual prop is a grenade. The user may acquire the grenade by controlling the virtual object. The terminal may display the grenade around the waist of the virtual object.

The virtual prop may include two acquisition manners, specifically as follows.

Acquisition manner I: The virtual object obtains the virtual prop by picking.

In the acquisition manner I, the terminal may display a plurality of virtual props in the virtual scene. The plurality of virtual props may include throwing virtual props, remote virtual props, close-range virtual props, supplement props, and the like. The throwing virtual props may be the virtual props used by the virtual object through throwing, for example, grenades, smoke grenades, frangible grenades, and the like.

Specifically, the virtual prop may be displayed on the ground of the virtual scene or the virtual item. In a case that a distance between the virtual object corresponding to the terminal and the virtual prop is less than a target threshold (for example, 1 m), the terminal displays a pickup option of the virtual prop on an upper layer of a virtual environment picture. In a case that a trigger operation for the pickup option is detected, the terminal may control the virtual object to pick up the virtual prop. Upon the completion of pickup of the virtual props, the virtual prop is displayed at a target part of the virtual object in the virtual scene, thereby indicating that the virtual object is equipped with the virtual prop.

The target part may be hands, shoulders, the back, or the like, which is not limited in the embodiment of this disclosure. the target threshold may be preset by a person skilled in the related art according to requirements, which is not limited in this embodiment of this disclosure.

Acquisition manner II: The virtual object obtains the virtual prop by calling.

In the acquisition manner II, the terminal may display a call control. In a case that the user is to call the virtual prop, a trigger operation may be performed on the call control. Then the terminal receives a trigger signal of the call control to generate a creation instruction, so as to create the virtual prop in response to the creation instruction. The call control is configured to call the virtual prop to enter the virtual scene. The form of the call control may be a button displayed on the upper layer of the virtual environment picture.

For the virtual prop, the user may control, by means of operations, the virtual object to use the virtual prop. In a possible implementation, the terminal may further display a trigger control of the virtual prop on a graphical user interface. The trigger control is configured to detect a throwing operation of the user to control the virtual object to control the throwing of the virtual prop by using a throwing control.

A throwing process of the virtual prop is described by using a specific example below. As shown in FIG. 5, the terminal may display the virtual object equipped with the virtual prop in a display option 501 of the virtual prop in the graphical user interface. In a case that the user wants to use the virtual prop, the user may select the virtual prop and trigger the trigger control 502 to complete the throwing operation. A quantity of the trigger controls 502 may be one, or may be two or more than two, which is not limited in the embodiment of this disclosure.

the trigger control 502 may be a trigger control of other virtual props or a trigger control of other actions before the user selects the throwing virtual prop. For example, in a case that the user selects a firearm virtual prop, the trigger control 502 may also be referred to as a shooting control. In a case that the user does not select any virtual prop, the trigger control 502 may be a punch control. However, in a case that the user selects the throwing virtual prop, the trigger control 502 may be referred to as the throwing control.

In a possible implementation, the terminal may display the trigger control 502 according to a display style corresponding to a current state of controlling the virtual prop. For example, in a case that the trigger control 502 is the shooting control, the display style of the trigger control 502 is a bullet displayed in the center of the button. In a case that the trigger control is the throwing control, the display style of the trigger control 502 is a grenade displayed in the center of the button. In a case that the trigger control 502 is the punch control, the display style of the trigger control 502 is a fist displayed in the center of the button.

In a possible implementation, in a case that the virtual prop is in a selected state, the terminal may further acquire and display a candidate movement trajectory of the virtual prop according to a viewing direction of the current virtual scene. Specifically, the terminal may determine a throwing angle of the virtual prop according to the viewing direction of the current virtual scene. The candidate movement trajectory of the virtual prop is acquired and displayed according to the throwing angle.

For example, as shown in FIG. 6, the user selects the virtual prop, and the terminal may display the display option 501 of the virtual prop in a highlighted state. In a case that the terminal detects the trigger operation on the trigger control 502, the trigger operation being the throwing operation, the terminal may display the candidate movement trajectory 504 according to the throwing angle corresponding to a current viewing angle. The user may adjust the viewing angle as required. The terminal may adjust the candidate movement trajectory 504 according to the viewing angle adjustment, and stop the trigger operation on the trigger control 502 until the user is satisfied, so as to control the virtual prop to be thrown out. The candidate movement trajectory 504 in a case that the virtual prop is thrown out is the first movement trajectory. Before the user stops the trigger operation, the terminal may further display a cancel throw button 503. The user may trigger the cancel throw button 503 to stop the throwing operation.

In a possible implementation, the virtual prop may further have a fixed release time. In a case that the throwing time of the virtual prop reaches the release time, the virtual prop triggers the release effect. The throwing time refers to an elapsing period of time after the throwing operation is received, and the release times corresponding to different virtual props may be the same or different. For example, in a case that the virtual prop is a virtual smoke grenade, the release time is 4 s, and the release effect is to release smoke within a designated range. In a case that the virtual prop is a virtual flash bomb, the release time is 5 s, and the release effect is to release a flash within the designated range.

Specifically, the terminal may further display the remaining release time of the virtual prop in the graphical user interface when detecting the trigger operation on the trigger control. For example, as shown in FIG. 7, the user may display the remaining use duration 505 in the interface after holding the trigger control 502. The remaining use duration of 4 s is used for indicating that the virtual prop is to trigger the release effect after 4 s.

in a case that the user stops holding the trigger control 502, the virtual prop is thrown out, and the terminal may further continuously display the remaining use duration 505. As shown in FIG. 8, in a case that the virtual object is equipped with one throwing virtual prop, a state of the virtual object is switched back to a state of controlling the firearm virtual prop, and the remaining use duration 505 is displayed in the interface. The remaining use duration of the throwing virtual prop is 1 s. In a case that the virtual object is equipped with a plurality of throwing virtual props, the terminal may display the virtual object in a state of using the next throwing virtual prop. This situation may be shown in FIG. 5 or FIG. 6, and the details are not described herein again.

In a possible implementation, in step 401, the terminal may further display the first movement trajectory of the virtual prop. In this way, the user can observe the movement of the virtual prop more intuitively and clearly. Specifically, the terminal may acquire and display the first movement trajectory of the virtual prop in response to the throwing operation on the virtual prop, and display the movement of the virtual prop along the first movement trajectory in the virtual scene.

402: The terminal transmits a throwing instruction to the server.

The terminal may further transmit the throwing instruction to the server in response to the throwing operation. The throwing instruction is used for informing the server of related information of the virtual prop when being thrown. Information in the throwing instruction may be used as a data basis for the server to determine the second movement trajectory of the virtual prop.

In a possible implementation, the throwing instruction may include a location and a throwing angle at which the virtual prop is thrown. The location and the throwing angle at which the virtual prop is thrown may be used for determining the first movement trajectory or the second movement trajectory of the virtual prop.

403: A server acquires a second movement trajectory of a virtual prop in response to a throwing instruction on the virtual prop.

The server may also extract the location and the throwing angle from the throwing instruction, and acquire the second movement trajectory (for example, the determined throwing angle based on the throwing angle is a parabolic trajectory of a starting point) according to the location and the throwing angle. A process of acquiring the second movement trajectory is similar to a process of acquiring the first movement trajectory by the terminal in step 201, and the details are not described herein again.

the first movement trajectory and the second movement trajectory are respectively movement trajectories of the virtual props obtained by the terminal and the server. Since some virtual scenes and angles in the terminal and the server may not be exactly the same, and the first movement trajectory and the second movement trajectory obtained by the terminal and the server may be not the same, the terminal and the server may perform step 404 to step 407 below to correct the first movement trajectory and the second movement trajectory to a same movement trajectory.

404: The terminal acquires collision information and movement information of the virtual prop in response to a collision between the virtual prop and a virtual obstacle on the first movement trajectory.

405: The terminal transmits, to the server, synchronization information including the collision information and the movement information.

In a case that the virtual prop collides with the virtual obstacle on the first movement trajectory, the terminal may acquire the collision information and the movement information of the prop to synchronize the collision information and the movement information to the server. By using step 404 and step 405, the collision information and the movement information of the virtual props in the terminal and the server are the same, and the calculated first movement trajectories are the same, so that the subsequently determined target release locations are also the same. Therefore, by using the step of synchronization, the subsequent display location of the release location of the virtual prop is accurate and has a desirable display effect.

In a possible implementation, the virtual prop may include a plurality of types. Some virtual props may rebound after colliding with the virtual obstacle, for example, the grenade, the smoke grenade, and the like. In addition, some virtual props do not rebound (that is, the virtual props have adhesive properties) after colliding with the virtual obstacle, for example, sticky grenades (grenades having adhesive properties can be adhered to a first object coming into contact with the grenades after being thrown). For the virtual props that do not rebound, a situation that the target release locations calculated by the terminal and the server are not the same will not occur. Therefore, the method may be only used in such virtual props (that is, the virtual props having no adhesive properties, or the virtual props having rebound properties) that can rebound.

In the implementation, type information of such virtual props that can rebound is a target type. The terminal may acquire the type information of the virtual prop to determine whether the type information of the currently controlled virtual prop is the target type. If so, the terminal may perform step 405. If not, the terminal does not need to perform step 405. The virtual prop belonging to the target type has no adhesive properties.

Specifically, the terminal may perform, in response to the collision between the virtual prop belonging to the target type and the virtual obstacle on the first movement trajectory, the step of transmitting the collision information and the movement information of the virtual prop to the server.

Optionally, the terminal may also display the release effect of the virtual prop at the collision location information in response to the type information of the virtual prop not being the target type. For example, as shown in FIG. 9, the user controls the virtual object to throw a sticky grenade 900. The sticky grenade 900 is stuck to a wall after colliding with the wall in the virtual scene. The terminal may display an explosion animation at the location.

406: The server receives the synchronization information transmitted by the terminal.

407: The server corrects the second movement trajectory according to the collision information and the movement information.

The server receives the collision-related information synchronized by the terminal, and may reacquire the second movement trajectory according to the collision information and the movement information to correct the original second movement trajectory.

For the collision information, the collision information may include different information. In a possible implementation, the collision information may include the collision location information. It may be understood that, the virtual prop starts from the collision location to continuously move in a certain direction after the collision. Therefore, a starting point of the movement after the collision of the virtual prop can be synchronized by synchronizing the collision location information.

In another possible implementation, in addition to the collision location information, the collision information may further include other information, for example, type information of the virtual obstacle. In the implementation, the virtual obstacles having different type information have different rebound coefficients. The rebound coefficient of the virtual prop during the rebounding may be determined by synchronizing the type information of the virtual obstacle, so that a velocity after the rebounding may be calculated based on the rebound coefficient.

For the movement information, the movement information may be movement velocity information of the virtual prop during a collision, or may be movement velocity information of the virtual prop after the collision. The movement velocity information may be a movement velocity. The two movement velocities are both a vector, including both a magnitude and a direction. The movement velocity information after the collision may be calculated by using the movement velocity information and the collision location information during the collision. The second movement trajectory after the collision may also be calculated by using the movement velocity information and the collision location information after the collision. The embodiments of this disclosure do not limit the specific information type of the collision information and the movement information.

In view of different collision information and different movement information, three possible situations for determining the second movement trajectory are provided below.

Situation I: The collision information includes the collision location information, and the movement information includes the movement velocity information of the virtual prop during the collision. Optionally, in response to the collision between the virtual prop and the virtual obstacle on the first movement trajectory, the terminal acquires the collision location information and the movement velocity information of the virtual prop during the collision, uses the collision location information as the collision information, and uses the movement velocity information of the virtual prop during the collision as the movement information.

Correspondingly, the process of determining the second movement trajectory may be as follows. The server acquires the movement velocity information of the virtual prop after the collision according to the collision location information and the movement velocity information of the virtual prop during the collision. A collision location indicated by the collision location information is used as a starting point, and the movement velocity information after the collision as initial movement velocity information. The second movement trajectory of the virtual prop after the collision is acquired.

In the situation I, the information synchronized by the terminal to the server is the information during the collision. The server needs to acquire the information of the virtual prop after the collision according to the information during the collision. It may be understood that the collision location information is a starting point of the second movement trajectory. The movement velocity information after the collision may be calculated based on the movement velocity information before the collision. In a case that the starting point and the initial movement velocity information are determined, the second movement trajectory may be calculated. The movement velocity information of the virtual prop after the collision may also be referred to as a rebound velocity, which reflects a movement direction and the velocity magnitude after the rebounding. Situation II: The collision information includes the collision location information and the type information of the virtual obstacle. The movement information includes the movement velocity information of the virtual prop during the collision. Correspondingly, the process of determining the second movement trajectory may be as follows. The server acquires rebound information corresponding to the virtual prop according to the type information of the obstacle, and determines the movement velocity information of the virtual prop after the collision according to the collision location information, the rebound information, and the movement velocity information of the virtual prop during the collision.

In the situation II, the virtual obstacles having different type information correspond to different rebound information. In a case that the movement velocity information before the collision is the same and the rebound information is different, the acquired movement velocity information after the collision is also different.

In a possible implementation, the rebound information may be the rebound coefficient, which is a coefficient in the calculation method for calculating the movement velocity information after the collision. In a specific possible embodiment, the type information of the virtual obstacle may include first type information and second type information. The first type information corresponds to a first rebound coefficient, and the second type information corresponds to a second rebound coefficient. Correspondingly, in the foregoing steps, the server acquires the first rebound coefficient corresponding to the first type information in response to the type information of the virtual obstacle being the first type information, and acquires the movement velocity information after the collision according to the collision location information, the first rebound coefficient, and the movement velocity information before the collision. The server uses the collision location information as the starting point, uses the movement velocity information after the collision as the initial movement velocity information, and acquires the second movement trajectory of the virtual prop after the collision.

For example, the type information of the virtual obstacle is shown in FIG. 10 and FIG. 11. The virtual obstacle having the first type information may be a virtual item 1001 in the virtual scene, for example, a wall, the ground, and the like. The virtual obstacle having the second type information may be a virtual object 1002 in the virtual scene. In a specific possible embodiment, the first rebound coefficient corresponding to the first type information may be greater than the second rebound coefficient corresponding to the second type information. Correspondingly, under a same throwing condition, the movement velocity of the virtual prop after colliding with the virtual obstacle corresponding to the first type information is greater than the movement velocity of the virtual prop after colliding with the virtual obstacle corresponding to the second type information. Definitely, other situations may also exist. For example, the first rebound coefficient is less than the second rebound coefficient, which is not limited in the embodiment of this disclosure.

Compared with the situation I, since the rebound information of the virtual obstacle is added, a rebound effect of the virtual prop after colliding with different types of virtual obstacles can be simulated, thereby improving the authenticity of the rebound effect of the virtual prop.

Situation III: The collision information includes the collision location information, and the movement information includes the movement velocity information of the virtual prop after the collision. Correspondingly, the process of determining the second movement trajectory may be as follows. The server uses the collision location information as the starting point, uses the movement velocity information of the virtual prop after the collision as the initial movement velocity information, and acquires the second movement trajectory of the virtual prop after the collision.

In the situation III, the terminal directly synchronizes the movement velocity information of the virtual prop after the collision to the server. The server may obtain the second movement trajectory by calculation according to the collision location information and the movement velocity information.

In a possible implementation, during the acquisition of the collision information and the movement information of the virtual prop, the terminal acquires the collision location information (determined as the collision information) in response to the collision between the virtual prop and the virtual obstacle on the first movement trajectory, and determines the movement velocity information (determined as the movement information) of the virtual prop after the collision based on the collision location information and the movement velocity information of the virtual prop during the collision.

Optionally, during the determination of the movement velocity information after the collision, in order to simulate a collision rebound effect of an object in the real world more realistically, the terminal acquires the rebound information corresponding to the virtual prop based on the type information of the virtual obstacle, thereby determining the movement velocity information of the virtual prop after the collision based on the collision location information, the rebound information, and the movement velocity information of the virtual prop during the collision. For the process of determining the movement velocity information after the collision by the terminal, reference may be made to the process of determining the movement velocity information after the collision by the server, and the details are not described herein again in this embodiment.

Compared with the situation I and the situation II, since the process of determining the movement velocity information after the collision is performed on a terminal side, the server only needs to determine the movement trajectory based on the collision location information and the movement velocity information. Therefore, the parallel processing pressure of the server can be reduced.

408: The server determines a target release location of the virtual prop according to the corrected second movement trajectory.

The target release location may be determined by the server based on the second movement trajectory of the virtual prop. In a possible implementation, the terminal may also determine the target release location based on the first movement trajectory of the virtual prop. The determination process is similar to the process of determining the target release location by the server, and the details are not described herein again.

In the implementation, the terminal may further compare, with the target release location determined by the server, the target release location determined by the terminal. In a case that the target release location determined by the terminal is the same as the target release location determined by the server, the terminal may perform step 411 below. In a case that the target release location determined by the terminal is not the same as the target release location determined by the server, the terminal performs step 411 based on the target release location determined by the server.

by using the foregoing step 404 and step 405, the terminal synchronizes the collision information and the movement information to the server during the collision of the virtual prop. The movement trajectories of the virtual prop determined by the terminal and the server are the same, and the information used for determining the target release locations is the same, so that the determined target release locations are also the same. Therefore, step 411 is performed based on the target release locations determined by using the foregoing method. The release effect of the virtual prop when reaching the target release location can be displayed at the target release location, and the location reached by the virtual prop is the same as the release location, thereby achieving an accurate display location and a desirable display effect.

For the process of determining the target release location, the virtual prop may include a plurality of release triggering manners. For example, the virtual prop is released when falling onto the ground. In another example, the virtual prop is released in a case that the throwing time reaches the release time. A plurality of possible implementations for determining the target release location are provided for the trigger manners below.

Manner I: The server determines a drop point of the virtual prop according to the corrected second movement trajectory and a location of the ground in the virtual scene, and determines the drop point as the target release location. In the manner I, the virtual prop is released when falling onto the ground. The target release location is the drop point of the virtual prop.

Manner II: The server determines, as the target release location according to the corrected second movement trajectory and the throwing time of the virtual prop, a location where the virtual prop on the second movement trajectory is located in a case that the throwing time reaches the release time. In the manner II, the virtual prop is released in a case that the throwing time reaches the release time. The server may time the throwing time of the virtual prop. In a case that the throwing time reaches the release time of the virtual prop, the location where the virtual prop is located is the target release location.

In the foregoing manners, the virtual prop has two trigger manners: the virtual prop is triggered when falling onto the ground, and is also triggered in a case that the throwing time reaches the release time. Therefore, the server may determine whether the virtual prop falls onto the ground first, or the release time is reached before the falling onto the ground. Once any one option is satisfied, the target release location can be determined.

In the foregoing manners, the process of determining the drop point of the virtual prop by the server may specifically include: acquiring, by the server, an intersection point of the corrected second movement trajectory and the ground in the virtual scene, and using the intersection point as the drop point of the virtual prop.

the first movement trajectory and the second movement trajectory of the virtual prop are parabolas. The terminal may detect whether the virtual prop collides with the virtual obstacle during the movement according to the first movement trajectory. The detection process may be implemented in a manner of radiographic testing.

In a possible implementation, the terminal generates a ray of a target length based on the location of the virtual prop on the first movement trajectory. A direction of the ray is a tangential direction of the location of the virtual prop on the first movement trajectory. The terminal determines, in response to the intersection between the ray and the virtual obstacle, that the virtual prop collides with the virtual obstacle.

Specifically, the virtual prop during the movement may emit the ray of the target length in the tangential direction corresponding to the location where the virtual prop on the first movement trajectory is located. In a case that the ray passes through the virtual obstacle, the virtual prop collides with the virtual obstacle. The target length may be set by relevant technical personnel according to requirements. For example, the target length may be a small value, which is 1 centimeter (cm). This is not limited in this embodiment of this disclosure.

For example, as shown in FIG. 12, the virtual prop moves according to the first movement trajectory 1200. The virtual prop may emit a ray AB forward when moving to a current location. In a case that the ray AB passes through the virtual obstacle, the virtual prop collides with the virtual obstacle. In a case that the ray does not pass through the virtual obstacle, the virtual prop does not collide with the virtual obstacle.

In a possible implementation, the terminal may collide with the virtual obstacle on the first movement trajectory once, or twice, or even more than two times. That is to say, the number of times the virtual prop collides with the virtual obstacle on the first movement trajectory is at least once. As shown in FIG. 13, the virtual prop may collide with a plurality of virtual obstacles in the virtual scene a plurality of times. The virtual prop may collide with other obstacles again and rebound again after colliding with the one obstacle and rebounding.

In the implementation, the terminal may perform step 405 and transmit the collision information and the movement information to the server. The server and the terminal synchronize the collision information and the movement information during the at least one collision, thereby correcting the second movement trajectory according to the information. That is to say, the second movement trajectory is corrected based on the collision information and the movement information during the at least one collision. In this way, once the collision occurs, the terminal and the server both synchronize the collision information and the movement information, so that the movement trajectory of the virtual prop in the terminal is the same as that in the server, thereby enhancing the accuracy of the movement trajectory of the virtual prop.

409: The server transmits the target release location to the terminal.

410: The terminal receives the target release location transmitted by the server.

The target release location is determined based on the second movement trajectory. Since the second movement trajectory is determined based on the collision information and the movement information of the virtual prop that are synchronized by the terminal, it may also be understood that the target release location is determined based on the collision information and the movement information of the virtual prop that are synchronized by the terminal. For the specific determination process, reference may be made to step 408.

411: The terminal displays a release effect of the virtual prop at the target release location in response to the virtual prop being at the target release location.

The release effect of the virtual prop may be displayed in the form of animation. In a possible implementation, different virtual props correspond to different release effects. For example, in a case that the virtual prop is a grenade, the release effect may be an explosion effect. In a case that the virtual prop is a smoke grenade, the release effect may be a smoke effect. In a case that the virtual prop is a stun grenade, the release effect may be a shock effect.

The server determines the target release location, and synchronizes the determined target release location to the terminal by using step 409 and step 410. The terminal may continue to control the virtual prop to move according to the first movement trajectory until the virtual prop is located at the target release location, so as to display the release effect of the virtual prop at the target release location. In this way, the display effect seen by the user is that the virtual prop reaches a certain location and is released at the location. Therefore, the location where the virtual prop is located is the same as the display location of the release effect.

In the foregoing step, after the virtual prop collides, the terminal may continue to control the virtual prop to move according to the first movement trajectory after the collision. Since the terminal and the server synchronize the collision information and the movement information, the terminal and the server determine that the movement trajectories after the virtual prop collides are the same. The target release location determined by using the second movement trajectory is a location on the first movement trajectory. Therefore, in a process of controlling the movement of the virtual prop, in a case that the virtual prop moves to the target release location, the terminal may display the release effect at the target release location, so as to reflect the release in a case that the virtual prop moves to the location.

In a possible implementation, the release of the virtual prop may further affect other virtual items in the virtual scene. For example, in a case that the grenades explode, boxes in the virtual scene may be blown up, vehicles in the virtual scene may be detonated, and the like. In step 409, the terminal may further display, when displaying the release effect, the effect of other virtual items affected by the release of the virtual prop.

Specifically, the terminal may acquire a release range (i.e., release location range) of the virtual prop according to the target release location, and play a target animation within the release range. The target animation is used for indicating that the virtual items within the release range in the virtual scene vary with the release of the virtual prop. The use of the grenades and other weapons in a real scene is truly simulated by means of the acquisition of the release range and the playback of the target animation, thereby improving the authenticity of the release of the virtual prop in the virtual scene.

In the embodiments of this disclosure, in a case that the virtual prop collides with the obstacle on the first movement trajectory during the movement according to the first movement trajectory, the collision information and the movement information of the virtual prop are synchronized to the server, so that the server may correct, according to the synchronized collision information and movement information, the second movement trajectory acquired by the server. In the foregoing data synchronization method, the movement trajectory of the virtual prop in the server is corrected by synchronizing the collision information and the collision-related movement information of the virtual prop, so as to be synchronized with the movement trajectory in the terminal. In this way, the movement trajectory of the virtual prop in the server is the same as that in the terminal, thereby enhancing the accuracy of the movement trajectory of the virtual prop. In addition, the movement trajectories obtained by the server and the terminal are the same, and drop points calculated by using the same movement trajectory are also the same. In this way, an explosion effect can be displayed at the drop point.

In addition, in the embodiments of this disclosure, the terminal determines the rebound information based on the type information of the virtual obstacle with which the collision occurs, so as to determine the movement velocity information of the virtual prop after the collision based on the rebound information and the movement velocity information of the virtual prop during the collision. The collision location information and the movement velocity information of the virtual prop after the collision are synchronized to the server. The server corrects the second movement trajectory determined by the server. Therefore, the authenticity of collision and rebounding of the virtual prop after being thrown in the virtual scene is improved, and the parallel processing pressure of the server is reduced.

A specific example is provided below. As shown in FIG. 14, a specific process of the method includes the following steps.

Step I: Only to-be-thrown weapons (that is, the virtual prop of the foregoing target type) have the function in this game. Therefore, a to-be-thrown weapon is required to be switched first. A player may press a fire button (that is, the trigger control 502) to enter a pre-aiming state after switching to the to-be-thrown weapon. At this point, a red parabola (that is, the candidate movement trajectory 504) is displayed. The parabola is a trajectory, displayed to the player, along which the to-be-thrown object is about to fly. The parabola is calculated in one frame from the current location, a reverse direction, and a configured flight velocity. Then, a point may be collected for each small section (that is, a point may be obtained by calculation for each small section). All of the collected points are transmitted to a special effect line, and then the special effect line forms a trajectory (that is, the candidate movement trajectory 504) according to the points.

Step II: The to-be-thrown weapon is thrown after released by the user. This is because after the finger is loosened, finger touch information on a screen is changed, and then a pop-up information is calculated. The pop-up information is to trigger a fire event, and then the to-be-thrown object (that is, a virtual prop) is thrown out. After the to-be-thrown object is thrown out, the player can switch back to the original weapon (that is, the firearm virtual prop) if equipped with only one to-be-thrown object.

Step III: The to-be-thrown object may collide with a lot of things (that is, obstacles) during flight. The to-be-thrown object emits a ray forward at a small distance during the flight. An AB line segment is used for radiographic testing of the emitted ray. Since the to-be-thrown object flies along the parabolic trajectory, a direction and a velocity of the AB line segment corresponding to each frame are changed. The direction of the AB line segment is the tangential direction of the parabola.

In a case that an object is detected by radiographic testing, the information (that is, the type information of the obstacle) of the object for the collision may be learned. Then a collision location (that is, the collision information) and a calculated rebound direction (that is, the movement information) are both synchronized to the server. The server changes the movement trajectory of the determined to-be-thrown object in the server according to a new location, direction, velocity (that is, the movement information after the collision).

Step IV: The to-be-thrown object explodes after falling onto the ground (released, the release effect being displayed). The explosion information (that is, information including the target release location) of the server shall prevail. The server transmits the explosion information to a client. The client controls the to-be-thrown object to explode only when receiving the explosion information.

All the foregoing optional technical solutions may be arbitrarily combined to form an optional embodiment of this disclosure, and details are not described herein again.

FIG. 15 is a schematic structural diagram of a data synchronization apparatus according to an embodiment of this disclosure. In this disclosure, a unit and a module may be hardware such as a combination of electronic circuitries; firmware; or software such as computer instructions. The unit and the module may also be any combination of hardware, firmware, and software. In some implementation, a unit may include at least one module. Referring to FIG. 15, the apparatus includes:
